Re: [tycho-user] ClassCastException: org.codehaus.tycho.osgitools.project.EclipsePluginProjectImpl
This suggests you've got two classes with the same name, but loaded in different (incompatible) classloaders. I suspect you've got an old version mentioned and when you do the change you've left a 0.10.0 somewhere.

You can reproduce this by downloading my MP3 Manager from https://max-server.myftp.org/trac/mp3m
 
and then setting the Tycho version in project com.siemens.ct.mp3m.tycho.parent either to 0.11.0 or 0.12.0-SNAPSHOT.
This error appears if also if I start with an empty mvn repo…, so deleting .cache and .meta does not help.
 
Any hints?
 
Thanks a lot.
